4. After adjustment is complete, tighten the hardware to 13
lb-ft (18 Nm).
Speed Balancing (Tracking) Adjustment
If the rider drifts to the right or left when the ground speed
levers are in the maximum forward position, the top speed of
each of these levers can be balanced. Only adjust the speed
of the wheel that is traveling faster.

turn (clockwise) increments until the rider travels (tracks)
straight.
